a three-year period in the mid-1960s, the Center moved from its Long Island location to Orlando, Florida, taking residence as a tenant activity at the then-Orlando Air Force Base, that installation subsequently becoming Naval Training Center Orlando in 1968 until its closure in 1999 pursuant to a 1993 Base Realignment and Closure Commission (BRAC) decision. In 1985, the by then renamed Naval Training Equipment Center (NTEC) became the Naval Training Systems Center (NTSC). In 1988, the Center moved from NTC Orlando to its present headquarters approximately 15 miles east of its former location and just south of the University of Central Florida campus. The main building complex named for its founding father, de Florez. On October 1, 1993, the Naval Training Systems Center became today's NAWCTSD. In 2003, the command was briefly renamed Naval Air Systems Command Training Systems Division (NAVAIR-TSD), but has since reverted to its original name. In 2005, the physical facility and property was also designated as an independent base named Naval Support Activity Orlando, making it the sole remaining active duty U.S. Navy installation in the Orlando area. At approximately 40 acres in size, NSA Orlando is the second smallest shore installation in the U.S. Navy. However, it is surrounded by several "Partnership" buildings owned and maintained by the State of Florida and effectively leased at cost to various modeling, simulation and training (MS&T) commands of the Department of Defense, to include Army and Marine Corps commands, effectively increasing the military community to several hundred acres. The Air Force MS&T command in Orlando, the Air Force Agency for Modeling and Simulation (AFAMS), currently leases commercial office property immediately adjacent to, but outside the fence line of, NSA Orlando. NAWCTSD remains a component of the Naval Air Systems Command, but continues to maintain a portfolio and lines of effort that extends beyond Naval Aviation, to include other activities of the Navy and is a collaborative partner with other DoD and non-DoD organizations. Naval Support Activity Orlando The land and main buildings on which the main NAWCTSD facility is located inside the Central Florida Research Park is a U.S. Government installation that was designated as Naval Support Activity Orlando in 2005. Additional nearby buildings and facilities are shared in partnership with the Central Florida Research Park and the University of Central Florida and house other Department of Defense (DoD) and Department of Homeland Security (DHS) activities, to include
